The above is not my pic but it was just so adorable that I needed to add a fic to it. The person who made this is my hero.
"What the fuck is that?" Kate practically screeched in Castle’s ear. They were playing Halo—or rather he was playing and she was just smashing buttons. Castle had been trying for the past half hour to teach her how to use her weapons and who she was supposed to shoot. They were on opposite teams, but he refused to take advantage of the fact, allowing her to kill his character twice already.
Now he was attempting to let her play on her own, but she seemed to forget everything he taught her the second he unpaused the game.
"That would be a bazooka," Castle replied. "Surely you’ve seen one before in movies and stuff. Hell, you vaporized my character with it the first time."
"I know, I know! It’s just…jeez that looks a little exaggerated, doesn’t it?"
"Yeah, well it’s just a video game," Castle replied, chuckling. "They’re not exactly going for under-exaggerated. They’re trying to make it a little more intense, ya know?”
"I guess s—OOH OOH! DIE, BASTARD!"
"Kate, he was on your team!” Castle practically whined. He’d spent so long teaching her and now he was starting to get frustrated.
Kate deflated. “Oh,” she said, pouting. “Well, he comes back, doesn’t he?” Castle shook his head.
"That was his last life," he said, sadly. "You’re on your own, now."
Just then, another player walked onscreen and Kate shot him.
"HEY!" Castle cried.
Kate chuckled. “I take it that was your guy?” Castle nodded. “Now we’re even,” she giggled and Castle grinned at her.
"Oh, you are so on!” he exclaimed, before turning back to the screen and continuing to play. Kate did the same, her tongue poking out between her teeth as she concentrated, grinning madly when she saw his character show up on her screen.
She switched her handgun for a rifle and hid behind a rock, peeking over the top, while Castle was too focused with finding hers—he didn’t even think to look at her screen.
Kate used the scope and set her crosshairs on Castle before shooting.
Castle practically jumped out of his skin when his controller vibrated and his character slumped to the ground.
'Game Over' the screen read and Kate smiled in triumph, looking over at Castle, who stared at the screen, shocked.
"Whoa…" he said. "Good job, grasshopper."
"Well," she replied, "I had a pretty awesome teacher."
Castle grinned. “I am pretty awesome, aren’t I?” he said, cheekily.
Kate rolled her eyes. “Shut up, Castle,” she mumbled before leaning in and kissing him, softly. Castle reacted, immediately, dropping his controller and reaching up to cup her head with his hand, running his fingers through her silky hair.
When they pulled back, both were grinning.
"So," Castle said, wiggling his brows, "best two out of three?" He held up his controller.
Kate laughed. “You’re on!”
